胆管狭窄的临床X线诊断及误漏诊分析

Analysis on clinical radiographic diagnosis,misdiagnosis and missed diagnosis of biliary duct stenosis

目的:探讨胆管狭窄X线征象的特征,减少误漏诊病例。方法:回顾性分析63例经手术、病理证实的术前直接胆管造影的临床X线资料。结果:定位诊断正确49例,符合率为77%;定性诊断正确45例,符合率为71%;误诊6例,漏诊14例。结论:良恶性胆管狭窄分类在提高直接胆管造影定位和定性诊断结论中可发挥一定作用,减少误漏诊发生。

Objective ：To investigate the radiographic signs of biliary duct stenosis for reducing the cases of misdiagnosis and missed diagnosis.Methods：The data of preoperative cholangiography in 63 cases of biliary duct stenosis verified by operation and pathology were retrospectively analyzed.Results：There were 49 cases of correct loc＇,dizing diagnosis with diagnostic accordance rate of 77% ,45 cases of correct qualitative diagnosis with the d/agnostic accordance rate of 71% ,5 cases of misdiagnosis and 14 cases of missed diagnosis.Conclusion ：The classification of benign and malignant biliary duct stenosis may play a role in increasing the qualitative and localizing diagnosis and reducing misdagnosis and missed diagnosis.
